Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to an openable dome roof that enables a roof portion to be opened and closed in a building structure such as a stadium.

<Conventional technology> Currently, openable dome roof structures disclosed in technical journals include a structure in which a dome roof is divided into a plurality of parts and moved on both sides or in one direction, or one place on the outer periphery of a stadium. There is a structure where the dome roof opens and closes on both sides with this position as a fulcrum.

As one of these, for example, JP-A-61-274029
In this method, the dome roof is divided into approximately the same width in the radial direction, and is composed of a plurality of possible roofs bent into a spherical shape having the same sphere and different polar radii, and both ends of the roof are erected around the outer wall periphery. An openable dome roof supported by a guided guide member and moved in parallel on the guide is disclosed.

Separately, Japanese Unexamined Patent Publication No. 61-257560 discloses a stadium with a roof that can be opened and closed by dividing a dome roof into two pieces having substantially the same shape and movable along guides provided on both sides of the dome roof. It has been disclosed.

Furthermore, Japanese Patent Application Laid-Open No. 61-225476 discloses that a plurality of movable arch beams arranged in parallel with each other and between adjacent arch beams are wound or bent around the ends of the arm beams when opened. In addition, there is disclosed an openable and closable air film roof comprising a double air film which is deployed along the arch beam at the time of closing and is stretched by injecting pressurized air into the inside.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional open / close system in which the dome roof is divided and moved horizontally, an extra storage space such as a guide rail for storing the moved roof is required immediately above the stadium. And it was not necessarily superior in design. Therefore, as a method of reducing the storage space, it is conceivable to increase the number of divisions of the dome roof and compactly store the dome roof. However, although this is excellent in design as seen in the above-mentioned fan shape, the number of divisions is small. When the number of dome roofs is increased, the opening / closing mechanism of the dome roof becomes complicated, and not only the stability of the entire structure is deteriorated, but also the maintenance is burdensome.

In addition, the opening rate of the conventional dome roof opening and closing mechanism is 100%.
When the dome was completely opened, the framework supporting the dome roof remained, and the same open feeling as in the open stadium was not obtained.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an openable dome roof having a relatively simple mechanism, high structural stability, and excellent economic efficiency. is there. Another object of the present invention is to provide an openable dome roof having a simple openable structure and excellent in operability, stability and design.

<Means for Solving the Problems> The present invention has been made in view of the above-mentioned objects, and the gist of the present invention is to provide a circular dome roof of a substantially circular architectural structure such as a stadium, where the dome roof is vertically arranged. It consists of a combination covered by what is divided by the overlapping main roof and sub-roof, the main roof is formed in a self-supporting arch shape, and erected from one end to the other end of the upper outer periphery of the building structure, By providing a track at the inner lower end of the main roof, and by providing a track also to the building structure outside the track, a circular track is formed as a whole, and the sub roof is formed in an arch shape, and The open / close dome roof is provided with turning means for rotating the circular orbit at both ends, and is supported on both ends by the circular orbit so as to be capable of standing independently.

Further, the main roof and the sub-roof form a planar shape in a ribbon shape, and provide two parallel linear tracks tangentially opposed to the circular track of the building structure, and the main roof has It is also possible to provide running means for moving along the straight track, and to erection such that the main roof is supported by the straight track via the running means.

<Operation> A circular track is formed by connecting the track provided inside the outer circumference of the main roof and the track above the outer circumference of the building structure outside the track, thereby forming a circular track. It can be rotated by turning traveling means such as wheels provided on the outer periphery. This rotation can be changed from the upper part of the outer periphery of the building structure to the inside of the non-rotating main roof member to be in the overlapping state, and the dome roof can be changed to the partially open state.

Furthermore, since the main roof is provided with a traveling means, it is possible to move tangentially to the circular track together with the sub-roof overlapped on the inner side of the main roof by turning movement, thereby making the dome roof completely open. it can. In addition, about the closure of a dome roof, the reverse of the opening is operated.

<Example> Hereinafter, an example of an openable dome roof according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing the open / closed state of an openable / closable dome roof 1 installed in a substantially circular stadium 2. The stadium 2 having a mortar shape is surrounded by a stand 3 for accommodating spectators. A competition ground 4 is provided in the center of the competition ground.

The dome roof 1 is divided into two curved ribbon-shaped members, one of which is a non-rotating main roof 5 and the stadium 2
And a sub-roof 6 that rotates along the outer edge of the outer wall, which is the outer periphery of the stadium. The entire upper surface of the stadium 2 is covered in a state where both sides of each roof are overlapped. A rail 7 as a track for rotating the sub-roof 6 is laid one step higher than the outer periphery of the stand 3, and this rail 7 is connected to a rail 8 as a track provided on the inner periphery of the main roof 5, A circular orbit is formed as a whole.

On the other hand, in order to move the main roof 5 in the horizontal direction along with the sub-roof 6 superimposed on the inside by the turning movement, the rail as a track tangentially to a position opposite to the circular track is provided on the outer periphery of the main roof 5. 9 are laid in parallel.

Next, the opening / closing mechanism of the openable dome roof having the above configuration will be described.

1 and 2, a wheel 10 connected to a turning traveling device (not shown) provided on an outer peripheral portion of the sub-roof 6 travels on a rail 7 laid on the circular track to form a sub-roof. 6
Rotates in the direction of the arrow on the circular orbit (FIG. 1 (a)). When rotated 90 degrees, the sub-roof 6 moves to the rail 8 laid inside the outer periphery of the main roof 5, and as a result, the main roof 5
(FIG. 1 (b)). next,
The main roof 5 containing the sub-roof 6 travels on rails 9 laid by wheels 11 connected to horizontal traveling devices (not shown) provided on both sides of the main roof 5, and when moved horizontally, the stadium 2 Is completely open (FIG. 1 (c)). Also, by performing the above-described states in the reverse order, the stadium 2
Can be completely covered with the dome roof 1 again.
Furthermore, the auxiliary roof 6 can also reverse the rotation of the wheels 10 connected to the turning traveling device, and when opening and closing the dome roof 1, the rotation direction of the auxiliary roof 6 can be arbitrarily set. You can choose.

In addition, each roof is provided with a plurality of traveling devices at equal intervals on the outer peripheral portion thereof, and furthermore, since the guide roller 12 provided on the outer peripheral portion runs on the guide rail 20, the vertical direction,
A stable running state is maintained both in the horizontal direction. Further, since the main roof 5 and the sub roof 6 have the same spherical center and have a slight difference in the radius of curvature, they do not contact each other even when they rotate.

FIGS. 3 and 4 show another embodiment of the present invention in which the dome roof 19 is divided into three parts. The method of turning the auxiliary roofs 13 and 14 and the method of horizontally moving the main roof 15 are the same as those in the above-described embodiment.
Rails 16 and 17 as trajectories on which the radiators 3 and 14 rotate are respectively laid with different radii of curvature, and furthermore, rails 21 and 22 are provided inside the outer periphery of the main roof 15 and connected to the rails 16 and 17. The circular orbits of the books are laid concentrically on the same plane.

Next, the opening and closing mechanism of the dome roof 19 will be described. First, the sub-roof 14 is rotated in the direction of the arrow and moved to the lower part of the sub-roof 13 (FIG. 3A). Next, when the sub-roofs 13 and 14 are rotated together in the direction of the arrow (FIG. 3 (b)), the sub-roofs 13 and 14 shift to two rails laid inside the outer periphery of the main roof 15 respectively. As a result, it is housed on both sides of the main roof 15 (FIG. 3 (c)). In addition, sub-roof 13, 14
Is moved on rails 18 by horizontal traveling devices (not shown) provided on both sides of the main roof 15, and when it moves horizontally, the sky above the stadium 2 is completely open (No. FIG. 3 (d)). The dome roof 19 can be closed again by performing the above-described respective opening methods in the reverse order. However, at this time, the rotation direction of the sub-roof can be arbitrarily selected at the same time as the opening.

When the direction of rotation of the sub-roofs 13 and 14 is limited to the direction of the arrow shown in FIG. 3 (a), the method of stacking the dome roof shown in FIG. 5 can also be adopted. In this case, the respective rotating rails are laid just below the sub-roofs 13, 14 in the state of FIG. 3 (a). The rail laid on the stand 3 directly below the sub-roof 14 is connected horizontally at the same height to the rail 23 laid inside the outer periphery of the sub-roof 13, and the height of the rail 23 is changed to be directly under the sub-roof 13. The rails laid on the stand 3 are horizontally connected at the same height as the rails 24 laid inside the outer periphery of the main roof 15.

This opening / closing mechanism will be described. In FIG. 3, when the sub-roof 14 rotates in the direction of the arrow in the figure, it shifts to a rail inside the outer periphery of the sub-roof 13 and is stored inside the sub-roof 13 (FIG. 3 (b)). Next, the sub-roof 13 in which the sub-roof 14 is stored rotates in the direction of the arrow in the drawing, shifts to rails inside the outer periphery of the main roof 15, and is stored inside the main roof 15 (FIG. 3 (c)). ). In addition, the main roof 15 that houses the sub roofs 13 and 14
Travels horizontally on the rails 18 by a horizontal traveling device (not shown) (FIG. 3 (d)). In addition, the dome roof 19 can be closed by performing the above-described opening methods in reverse order.

In the present embodiment, as a method of moving the divided dome roof, a method of traveling on a rail and moving by wheels connected to each traveling device is adopted, but the method is not limited to this method, and compressed air, hydraulic pressure There is no hindrance as a running means utilizing magnetic levitation or the like.

The direction of horizontal movement of the main roof is not limited to the directions shown in FIGS. 1 and 3, but can be moved either upward or downward in the figure according to the purpose. When limited to one side, the rails 9 and 18 can be shortened. In addition, as shown in FIG. 3, a turning center axis is provided at the zenith where the main roof and the sub roof overlap to prevent deviation of the center of the turning roof,
It is also possible to make a smooth turn.

Furthermore, it is desirable that the series of opening and closing mechanisms of the openable dome roof according to the present invention be controlled by precise computer control in order to measure the stability of the entire dome roof during opening and closing operations.

<Effect> In the present invention, the dome roof can be opened by overlapping the main roof and the sub roof with a circular track. In addition, the dome roof is divided into a main roof and a sub-roof, and a simple opening / closing mechanism that rotates and moves horizontally is adopted. Many effects can be expected, such as excellent properties and design.

Further, the openable dome roof according to the present invention can be set to any open state from the closed state to the completely open state according to the purpose of use.
